Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the cross-sectional view of functionally gradient guide wheel provided by the embodiment of the utility model；
Fig. 2 is the main view of functionally gradient guide wheel provided by the embodiment of the utility model.
In figure: wheel hub 1, annular transitional layer 2, coating 3, bolt 4.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
All other embodiment obtained, fall within the protection scope of the utility model.
As Figure 1-Figure 2, the utility model embodiment provides a kind of functionally gradient guide wheel, comprising: wheel hub 1 and annular
Transition zone 2, the wheel hub 1 are detachably connected with the annular transitional layer 2, and 2 outer surface of annular transitional layer is equipped with coating 3.
Thus structure is it is found that guide wheel includes three parts: wheel hub 1, annular transitional layer 2 and coating 3, annular transitional layer 3 play connection
The effect of transition, therefore, the material of three parts can be selected according to the requirement of actual condition, in the actual use of guide wheel
In the process, the crocking resistance in the external surface work face of guide wheel is required it is high, mechanical strength to the transition zone 2 of guide wheel and
Toughness reguirements is relatively high, is directed to the use demand in actual condition by the different mechanical performance of setting different parts, not only
Material property and architectural characteristic are made full use of, material can be also saved, thus to improve the overall performance of guide wheel and service life.
Wherein, be detachably connected between annular transitional layer 2 and wheel hub 1, coating 3 by the technologies such as spraying, laser melting coating or 3D printing come
Coated in 2 outer surface of annular transitional layer.Therefore, after being damaged for damageable zone annular transitional layer 2 or coating 3, only need by
Annular transitional layer 2 and wheel hub 1 dismantle replacement, do not need wheel hub of dismantling, and while saving material, also improve maintenance effect
Rate also reduces maintenance cost.
Further, 3 material of coating is bidery metal.Bidery metal tissue characteristics: hard phase is uniform-distribution on soft phase matrix
Particle, soft phase matrix make bidery metal have extraordinary embedding hiding property, compliance and seizure resistance, and after adjustment, in soft base body
Recessed, Hard Inclusion evagination makes to form minim gap between sliding surface, becomes store oil space and grease channel, is conducive to antifriction, improves
Wear-resisting property；Convex Hard Inclusion play supporting role, and is conducive to carry.Therefore the bidery metal coating can effectively improve guide wheel table
The wearability in face improves the whole service life of guide wheel.
Further, the material of annular transitional layer 2 is 40Cr or manganese alloy.Thus structure it is found that 40Cr or manganese alloy not
Only there is high-intensitive mechanical performance, also there is certain toughness, annular transitional layer 2 primarily serves the work of carrying in guide wheel
With also suffering from shock loading and vibration, therefore while the annular transitional layer can be carried effectively, moreover it is possible to absorb shock loading and
Vibration.
Further, the periphery of the annular transitional layer 2 is completely covered in coating 3, and forms the outer circle of the guide wheel
Working face.Thus structure is it is found that coating 3 covers the periphery of annular transition zone 2 comprehensively, in guide wheel work, only coating 3
Outer surface be contact surface, annular transitional layer 2 will not be worn because of friction, and all extraneous frictions all occur with wear-resisting property
Coating 3 on, improve the service life of guide wheel.
Further, it is equipped with first step on the outside of wheel hub 1, corresponding with first step the is equipped on the inside of annular transitional layer 2
The height of two steps, the first step and the second step is equal.Thus structure is it is found that as shown in Figure 1, wheel hub 1 and ring
Shape transition zone 2 is equipped with corresponding step, and first step and second step just cooperate, and assembly is then tightened by bolt 4.
Step can effectively bear to mitigate the shear stress of bolt 4 from radial load, improve wheel hub 1 and annular transitional layer 2
Assemble intensity.
Further, it is connected between wheel hub 1 and the annular transitional layer 2 by bolt 4.Thus structure is it is found that pass through spiral shell
Wheel hub 1 is connect by bolt 4 with annular transitional layer 2, and is tightened with nut, convenient for disassembly and assembly in this way, and bolt semi-finals degree is high, can bear to come
From extraneous stretching, compression and shear stress.
Further, "O"-ring is additionally provided between the seal face of bolt 4 and the wheel hub 1 or the annular transitional layer 2.
Thus structure is it is found that bolt 4 compresses "O"-ring, to indirectly compress wheel hub 1 and annular transitional layer 2, "O"-ring is rubber
Circle or the soft quoit of matter, can play good sealing function, avoid guide wheel in actual working environment by dust or sand
The invasion of gravel and influence whole mechanical performance, while "O"-ring matter is soft, and bolt 4 is facilitated to press wheel hub 1 and annular transitional layer 2
Tightly, and "O"-ring is when by shock loading, moreover it is possible to absorb part and shake, play the operation of damping.
Further, bolt 4 is at least 3, and the bolt 4 is distributed along 1 central symmetry of wheel hub.Thus structure can
Know, multiple bolts 4 can be reinforced assembling intensity, and the symmetrical of bolt 4 can disperse uniform force, and stress is avoided to concentrate and damage
Bad bolt 4 extends the service life of bolt 4.
Compared with prior art, the utility model has the following beneficial effects:
1, by the way that guide wheel is divided into multiple functional modules, a guide wheel entirety is assembled by different functional modules,
